Regulated converter delivers PoE compliant power from a 12V source

Murata has introduced a new regulated converter. The SPC-54/4.4-L12PG-C is designed to deliver isolated 54V Power Over Ethernet (PoE) at up to 240W. The highly-compact SIP (Single Inline Package) module can power up to nine PoE devices at 25.5W from a 12V source. The SPC-54/4.4-L12PG-C was developed to deliver power to Ethernet devices over traditional Cat 5 network cables in accordance with IEEE 802.3 PoE requirements. This unique PoE source module is designed to operate in applications that support a 12V power source, converting 12V to 54V at 240W, to power and support multiple PoE devices. Proprietary circuit architecture provides a 94% efficient, PoE compliant, 54V output. The module provides PoE safety requirement that include input to output isolation at 2,250Vdc with basic insulation, Over Voltage Protection that meets SELV requirements. The module is packaged in a SIP format to save board space, and to optimize Pout capabilities in demanding applications. ? dvanced thermal management allows 240W of power at 60C in a very compact package. Total PCB board space required is just 67mm x 8.9mm. With a Vin range of 10.5V to 13.2V, the SPC-54/4.4-L12PG-C is suitable for resource-efficient, end-to-end information and communications technology (ICT) ecosystems that utilize PoE devices. These devices might include: VoIP phones, IP cameras, wireless access points, IPTV decoders, network routers, network switches, network Intercoms, Industrial sensors, keyless access systems and lighting controllers.
